WILLIAM MUNROE, OF WEST AUBURN, MAINE.

SOLE-CUTTING MACHINE.

Specification of Letters Patent No. 25,758, dated October 11, 1859.

To all whom it 'may concern:

Be it known that I, W. MUNROE, of 1West Auburn, in the county of Androscoggin and State of Maine, have invented a new and Improved Machine for Cutting Out Boot and Shoe Soles; and I do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a side sectional view of my invention. Fig. 2, is a front view of ditto. Fig. 2, is a horizontal section of ditto taken in the line w, Fig. 1.

Similar letters of reference indicate correspending parts in the several figures.

The invention consists in the peculiar for operating the arbor and die both as regards vthe rotating and up and down movement and the gaging or determining of the length of each movementl as hereinafter set forth.

The invention further consists in a novel means employed for operating a gage whereby the same at the proper time serves as a stop to insure the proper adjustment of the leather beneath the die and is removed at the proper time to permit the cut soles and refuse to be discharged from the platform previous to each cut of the die.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, represents a platform which is supported at a suitable height by a framing B, and C, is a cylindrical hard wood block which is inserted in the platform A, its upper surface being flus with the platform and its lower .end resting on a bar or plate a, in the framing. This block is secured in proper position and prevented from casually turning by means of a set screw b. By loosening or unscrewing this set screw at any time the block C, may be turned and then secured at any point. This will be fully understood by referring to Fig. 1.`

D is an upright which is firmly secured to the framing B, and extends some distance above it. To this upright two horizontal arms o, c, are attached one over the other in the same plane. These arms project over the platform A, and they serve as guides for a vertical arbor E, which is allowed to slide freely up and down therein. The upper end of the arbor E, passes through an arm d, the latter fitting in a recess in the arbor and below a wooden top portion e, which extends up through a horizontal plate or bar f, attached to two upright rods g, g, secured to the framing B. The arm cl, is attached to a vertical rod F, which slides in its arms c, C, and in another bearing 7L, near its lower end. The arm d, being attached to the arbor E, the latter will be raised with the rod F. This will be more particularly referred to hereafter.

In each side of the arbor E, two vertical slots i, c, are made. These slots at each side of the arbor are in line with each other, as shown clearly in Fig. 1. Each slot z', has an oblique or spiral slot j, communieating with it. These spiral slots form a communication between the lower vertical slots t', at one side of the arbor and the upper vertical slots i', at the opposite side. This will be fully understood by referring to Fig. 1, the dotted lines showing the form of the spiral slots at the back side of the arbor.

To the lower end of the arbor E, a plate Gr, is firmly attached. The form of this plate is plainly shown in Fig. 3. To the under side of the plate Gr, a similar plate H, is attached by bolts 7c, which are fitted in slots in the ends of plate G, see Figs. 1 and 3. To the under side of the plate H, a cutting flanch l, is attached or formed on said plate. This fianch is of the precise form designed for the soles to be cut and the fianch encompasses an opening m, in the plate H. The flanch Z, and plate H, form a cutting die and its operation will be presently shown.

Vithin the opening m, a block n, is placed. This block a, corresponds in form to the flanch Z, and its upper side is provided with a stem 0, which passes into the lower end of the arbor F, and has a spiral spring 29, placed above it, as shown clearly in Fig. 1.

To the upright D, there are two horizontal elastic bars g, r, attached. These bars have each a right angular projection s, at their outer ends and these projections fit in the recesses z', z", j, and perform functions hereinafter described.

In the lower part of the framing B, a horizontal shaft I, is placed. This shaft has a driving pulley J, on its outer end and a cam K, on its inner end, which acts as the shaft I, rotates against a pin 15,A on the rod .o the inner J, a part pinion L, is attached, the toot-hed portion of which as the shaft I, rotates gears into a pinion M, on a shaft N, to which astrap O, is attached, said shaft also having a spiral spring P, upon it which spring has a tendency to keep a pin u, at the inner side of the pinion M, in contact with a bar u, attached to the framing B. The strap O, passes over a guide j end o f the upright D, and' also passes around a pulley at, in the outer end of a horizontal arm 1', attached to the upper end lof said upright, the strap having a weight P, at tachedK to its end.

To the upright D, a guide a', and in this guide the upper end arbor or shaft Q, is' fitted and lower end of shaft Q, is fitted bearing Zn, said' bearingbeing fitted in suit'- able guides c', attachedr to the upright D. The shaft Q, is allowed to turn in its bearings, and to its lower endv a horizontal bar R, is attached, said har having an adjustable horizontal bar R, attached, the latter bar projecting over the platform and having a plate S, attached to it at right angles, the plate being attached to the har a set screw which passes through a slot aZ, in the plate into the bar as shown plainly in Fig. 3'. The plate S, performs the function of al gage and one end ofl it is bent downward at right angles as shown at e', Fig. 2 To thefinner side of bar R, a block f, is at'- is attached, of a vertical The works.

form a shoulderl g', and an inclined surface g, for av pin 71,, on the rod F, to act upon as' the latter rises and falfls, see Fig. 2.

T, is a gage whichA is securedv to the upper' A, by set screws surface of the' platform z', z', the latter passing through slotted arms j, attached at right angles to the gage T, as shown plainly in' Fig. 3.

The operation is as follows :"A; continuous rotary movement is given the shaft I, byl any convenient lution of the pulley J, the teeth of the part pinion L, will rotate the pinion M, of shaft N, and the strap O", will be wound on shaft N, and the weight P, elevated. Simultaneously with the raising the rod F, and arbor E, are raised by the action of the cani K, against the pin t. As the arbor E, rises it is rotated just one Yhalf of a revolution inconsequence of the projection s, of bar g, fitting in one of the spiral slots j, and when the arborv E, is fully raised the projection s, of the elastic bar 1, passes into the upper vertical sl'ot z", and serves as a stop to the arbor so far as regards its rotating movement. At this point the projection of thel bar r, is in the upper slot z, and the projection of bar g, in the' lower slot z", when the prominent side of the driving pulley' l portion of the part pinion pulley Vw, at the upper in a sliding vdown the stop borE, falls the pin it, in

power, and at every revo`l the shaft of the weight P,

portion ofthe cam K, passes the pin t, the arbor and rod F, drop by their own gravity andthe flanch Z, falls on the strip of leather U, shown in blue outline on the platform A, the flanch Z, falling on the leather directly over the block C, which is the bed. Just after the arbor E, has fallen the toothed L, passes the pinthen falls by its arbor E, forcinOr ion M, and the weight P, own gravity and strikes the strip' U, and cutting out therefrom a sole.

the block or bed C, an unnecessary distance' on account of the bar f, which' serves'` as astop for the weight P, preventing the latterv from acting beyond a certain distance on the arbor. As the' arborA E, again rises' u`n der the action' of the cam K, the sole withinj the flanch Z, is retained on the block or bed C, by' the block n, whichr is under the pressure of the spring p", until the flanch Z, is raised out of the leather stri-p. The block n, then rises with the arbor. It will be' seen'l therefore that the block n, serves to free or discharge the cut sole from the zanch, permitting the latterv to rise without carrying the sole with it. l

One side of the strip U, of leather'is p'lac'ed against the gage T, andv the' end' against the stop S. These parts insure the properl adjustment of the leatherU. Each time thel arbor E, rrises the operator shoves the cut sole oft the block C,y the stop S, beingraised to permit such result in consequence of the' pin tached. This bar is notched in order to y t, striking against theL shoulder g, of the blockv f', a spring j, on the shaft Q, forcing when the pin' It', passesv the' shoulder g, of the block f. When the afrpassing over the iii-- clrned surfacev g, of the block' f, forces the j stop S, out from' the fla-nch Z, so that the stopy cannot interfere with# the action of the iialnfch.` This is essential as it is necessary to have the' stop quite close to the fla-nch in or`- der to save as much stock` as possible. The stop as it falls is thrown back to its proper position by a spring lc. The spring p', on) N, turns the' pin u, directly in con-- tact with the' bar c, and insures the properrelative position or' disposition of the shaft N, and strap- O, for a succeeding operation as soon as the teeth of the part pinion have passed those of the pinion M. The block or bed C, is turned at any time as previously referred to in order to cause the bl-ock to be cut evenly by the flanch Z, the cutters being by that means distributed over its entire j surface. The' anch Z, in consequence of the v semi-rotation of the arbor E, at each upward j stock as possible.

I do= not claim the revolving die, nor the `the flanch Z, entirely through the' leathei als adjustable rotating bed, for they have been previously used, but,

Having thus described my invention What I claim as new and desire to secure by Let* ters Patent is,

l. The arrangement of the vertical slots z', z", in the arbor E, elastic bars Q, r, With their projections s, fitting respectively in said slots, the Weight p, bar f, and the shafts I, N, provided respectively With the cam K, spring p, pinion M, part pinion L, and strap O, substantially as described, to

operate the arbor F, and its die or cutting flanch Z.
